Heng Lee is a goatherd in the remote mountains north-east of Chiang Rai in northern Thailand, very close to the border with Laos. It is a tight-knit community where everyone knows one another.
Heng becomes sick all of a sudden, but not too sick to take the goats out, until one day he starts fainting, and needs help. There are no medical doctors in the neighbourhood, but the Shaman has been good enough for most people for centuries, so he visits her.
The Shaman takes some specimens and comes to the conclusion that Heng’s kidneys have stopped functioning and he, therefore, has little time left to live.
The battle is on to save Heng’s life, but there are other forces at work too.
What will become of Heng, his family and the rest of the community, if he takes the Shaman’s advice?
